2021 KIA TELLURIDE Forward Collision Avoidance Warnings Problems

Rear shock failure for the second time. This time in under 9 months. Front crash detection constantly goes off in cold snowy weather or rain. engine issue is frequent popping sound in exhaust and causing dirty oxygen sensors

On [XXX] my vehicle had a collision warning signal, then tire pressure, then brake lights and entire dash instrument panel. I parked the vehicle, then later in the evening test drove it again and the panel lit up again, in addition to the loss of the speedometer, tachometer, gear display, and drive mode display, so I immediately drove it to Courtesy Kia in Altoona, PA. On 4/18/25 Wendy Giordano of Courtesy Kia confirmed vehicle intake Courtesy Kia reset codes and was unable to replicate or diagnose a repair. The vehicle was returned on 4/23/25 despite my expressed concerns over safety. On [XXX] the vehicle again displayed the collision warning and the instrument panel lit up again, in addition to the loss of the speedometer, tachometer, gear display, and drive mode display. I got off the highway and limped the vehicle closer to my home, stopped for a brief time, and...

My main screen on my 2021 Telluride goes out suddenly, turning off the backup camera and collision warnings. Sometimes when I start the car it never turns on, sometimes it starts to boot and then goes out and sometimes it works for a few seconds/minutes and then turns off. Once and a while it turns on and stays on for days before going on randomly again.

The front bumper sensor has stopped working. This is preventing proper function of the forward collision warning and the parking collision warning. I took this to be fixed to Executive Kia of Wallinford, CT and they identified corrosion of the component as the cause of the failure. My car has had no accidents or damage to bumper so any corrosion is due to improper sealing of part, or weather proofing of bumper. An online search identified many other Kia owners dealing with this same issue. My extended warranty through Fidelity Inc sent out an inspector to review this and they are refusing to cover the cost of the fix since it is due to "corrosion." Including photos my Kia dealer mechanic sent me of the corrosion.

While driving the Kia Telluride, the forward collision avoidance warnings started flashing, then said it was failing, then the tire pressure system did the same, then the speedometer and tachometer failed as did the turn signals, gear shift, and lights. The car was becoming unsafe to drive. The car has been at the dealer for 3 weeks now, the dealer changed the Cluster Assembly-Instrument at at cost of $2600. Within 1/2 of leaving the dealership the same problem noted above began happening, again making the car unsafe to drive. In researching on line at the KiaTelluride forum there have been a large number of similar unsafe occurrences by other Kia Tellurides as reported by owners. This is a serious safety problem that has been noted numerous times. (I can't get my images of the 2 page dealer invoice for Cluster Assembly-Instrument $2600 that did not solve the problem to download...

On February 16th at about 6 AM, I was in a collision. I was first hit in the front by a pickup truck impacting my frontside, from right to left. I expected my Kia Telluride to engage it's safety features such as, Automatic Emergency Braking, Forward Collision Warning, and at the very least the Airbags, which none of them deployed at anytime during this collision. I was then rear-ended by an 18-wheeler; smashing my entire back window. The 18-wheelers' trailer that it was holding then slide down on the passenger side of my 2021 Kia Telluride. With that my vehicle was then pushed into the guardrail from the impact and power of the trailer falling on the passenger side. My vehicle has been inspected by my insurance company, Geico Inc. as they declared my vehicle a total loss. There was no warnings, or any indicators that my vehicles safety issues...

There were 2 lanes going in the same direction and I was on the right. The road was turning to the right and ended up hitting a car in the lane on the right. Road conditions were wet but no puddling. I depressed the brake pedal to reduce my speed for the turn, but and I kept going as if I hadn't hit it at all. By moving from the right to the left lane, the car was going up a slight bank. There was no skidding, no rumbling from the anti-lock, just a steady forward motion. I was so caught off guard with this unusual movement of the car that I thought my brakes had locked, so I didn't bother try turning the wheel.

TELURIDE 2021 OWNERS MANUEL, PAGE 5-64, 5-63 AND THE KIA” FEATURES AND FUNCTIONS GUIDE. “PAGE 15, SHOWS DIRECTIONS FOR USING THE FCA, OR FORWARD COLLISION AVOIDANCE. BUT THERE IS NO SUCH SAFEY OPTION IN THE CAR. FURTHER THE DRIVERS ASSIST - - - FORWARD SAFETY OPTION, SHOW IN THE OWNERS MANUEL, IS NOT ON MY ONBORD SCREEN. THERE IS NO DISCLAIMER SUCH AS “IF SO EQUIPPED”. FOR ME THIS IS A IMPORTANT KIA FAILURE.

Harness and wires damaged and chewed by woodchuck causing multiple warning lights and malfunctions including headlight; turning signal and temperature to suddenly stop working, resulting in front wiring harness replacement and repairs costing over $7k in damage.

While in drive, the battery discharge warning was displayed inconsistently, similar to what had occurred sporadically on January 21 and January 23. Without notice, multiple indicator lights started flashing, including low tire pressure, Safety features such as check forward collision assist system, and more. Power steering failed, and ultimately had to coast into a safe location. This resulted in a tow to the dealership, where after multiple days, the dealership found that the alternator failed and replaced it under warranty. This could have negatively impacted not only my safety but the safety of others as the vehicle safety features were not operational and I lost full functionality of the vehicle such as power steering loss. All regular maintenance and satisfaction of recalls had been completed by a Kia-authorized dealership before this event.

While driving in a parking garage and going down a ramp to the next level, all of the lights on my dashboard popped on and the brakes stopped working. The emergency brakes failed to work, and we crashed into a wall/air conditioning unit. Luckily, we were going slow since we were in a parking garage and did not hit another car, but if we were on a highway and/ my entire family were in the car, someone could have died not only in my car but in other cars. The vehicle has been inspected by the dealership, but only after 3 weeks, and I've had to call to get any sort of communication from Kia. They have been horrible with communication. They also have not offered guaranteed reimbursement for a rental car nor have they offered a loaner. Insurance has inspected the car from a collision perspective and gave a...

Had a new transmission installed in February 2022. Now, beginning March 13, warning lights come on to check blind spot and forward collision systems. About 10 seconds after the car lurches violently. This has happened at full speed on interstate which is a huge risk for injury/death. I have video of this phenomenon.

On my wished a small object hit my windshield on the passenger side and within an hour it spread more by the best day it was almost on the driver side of the windshield. Second, the forward collision and lane departure lights came on. I took the SUV to Kia they said it was an issue with the camera and they where going to order the part and replace it for me. It seem I was not the only one with this issue.
